Library as a keystone in "virtual university", its compelling advantage is taking maximum sharing of source such as libraries. In these libraries, people need not worry about quantity, daytime and area limited. It supports interlibrary lending among institutions. It makes it possible for scholars and researchers to obtain library resources from around the world without leaving their campuses or institutions.

Along with computer technology developing, "virtual university" will take more and more perfect for education. The actual university will use the best of the virtual university. .
Higher lever programming.
We all know that our operating systems and variety of software are written by computer-programming language. For many years ago, computer-programming language as an implement specify to professional programmer and engineer, such as machine language ("natural language", generally consist of string of numbers, 1s and 0s, any computer can directly understand.), assembly languages (English-like abbreviation to represent the elementary operations of computer.). Computer usage increased rapidly. To speed the programming process, high-level language were developed in which single statements could be written to accomplish substantial task. The term "higher level" means that many details are handled automatically so that programmer can write less code to get the same job done.
